Extrusion die is a key factor in tube extrusion deformation.
Owing to these attractive properties, it finds extensive use in applications such as combustion systems, turbines and nuclear reactors.
Woei-Shyan Lee did a research on Iconel 690 alloy about its mechanical property and micro morphology during high temperature and high strain rate[3].
Simulation results and analysis Extrusion force and temperature rise are important indicators in affecting steel tube extrusion process, during which extrusion force should be sought the minimum and temperature rise should be controlled in a limited scope.
On stable extrusion stage, billet is extruded at a constant speed, and extrusion force falls back to a certain point and fluctuates around average extrusion force under the influence of various factors.

Introduction Contemporary machine industry sets high requirements for mechanical and operational properties of machine parts.
Fig. 2 – Mechanical properties of TRIP 700 A standards solver of software package Abaqus 6.14-1 was used for the calculations.
All this entails aggregation of lightly deformed grains by means of other grains, and deterioration of steel mechanical properties later on.
On the basis of simulation results it has been concluded that position and orientation of the retained austenite grains are ones of the important factors, which affect the transformation.
In practice it can be useful for obtaining of higher strength with uniform distribution of the mechanical properties in the rod cross section.

There are many factors that affect fatigue life, such as the content of RAP, modified emulsion content, cement grade, gradation, cement content and so on.
So the stress intensity factor can be used to characterize da/dN under loading of constant amplitude
(16) Mathematical Decoupling Analysis of Rectangular Section Beam for Semi-flexible Cold Recycling Asphalt Mixtures Generally, mathematical decoupling analysis is to ignore or simplify one of the influence factors which have little or no effect.
However, many factors such as simulating effect, complexity driving load and so on should be further considered.

Relationships of paste properties and influential factors can be demonstrated with regression analysis.
Generally, the targeted physical and chemical properties of CPB are apparently affected by many parameters such as mobility, uniaxial compressive strength (UCS), yield stress and concretion time.
Paste Properties Test.
The UCS tests were carried out according to the China national standard for test method of mechanical properties on ordinary concrete (GB/T 50081-2002) [5].
Range Analysis of Influential Factors.

This means that the normal stress is minimal and the shear stress, together with the shear rate, should be the prime factors affecting the skeleton compression and thus the liquid motion.
In the case of a paste, it is necessary to separate the three factors which are in the interaction.
The rheological properties of a paste are mostly modified by the addition of suitable additives.
These factors cause the pressing of the skeleton created by the grains of powder, a decreasing of the volume of the voids and the migration of the liquid, whose meaning for the rheological properties of the paste is essential.
The density and strength of the agglomerates have the suitable properties.

Integral damage of material determines the level of mechanical and deformative properties of products.
The role of deformations in structural organization and formation of product properties.
Internal and external factors influence material at the same time.
At the same time, the limiting internal influences for surrounding systems (subsystems) pass from a rank of internal factors of influence into a rank of external factors with the relevant mechanism of realization.

Analysis of factors affecting pre-stressing loss in pre-stressing cable anchor and compensative measures[J].

Various steels with suitable properties can be used as barrel steel.
The main goal of the experiments was to analyze the friction properties and wear of steel for the production of stressed 34CrNiMo6 barrels in contact with a G40 bearing ball with a diameter of 6.35 mm.
The decrease in gun barrel life is mainly caused by a combination of heat, chemical factors, and mechanical factors.
The wear of small-caliber barrels is one of the key factors affecting barrel life.

Results and Discussion Mechanical Properties of Al-7 wt.% Si Alloy after B Refinement.
As shown in table 1 (casting), mechanical properties of Al-7 wt.% Si Alloy after B refinement.
Because the factors that affect the mechanical properties of binary alloy Al-Si alloy phase is mainly composed of phase, the homogeneous degree of morphology and structure.
Thick, brittle finer structure, distributed more evenly dispersed, the better mechanical properties.
In this case, the mechanical properties are also desirable.

To understand the microstructure properties and dimensional accuracy of the drill steel, a rigid plastic finite element method was used to analysis Mannesmann piercing in steel drilling production.
Feed angle and plug position directly affects the deformation of the metal, the rolling force, and the precision of the capillary size.
The friction factor between the billet work-piece and rollers is set to 0.7.
The billet is used 55SiMnMo steel which material properties show as table 1. 55SiMnMo is a kind of air cooled Bainitic steel.
